Products for Coldroom storage are selected from lists which are arranged in Food 'type' groups. Each group features a list of common products and for these all relevant thermal properties are stored in the program as default values. The default values include Specific heat above the product freezing temperature, Specific heat below product freezing temperature, the product freezing temperature and Latent Heat. Fruit and Vegetables, and the generic group described as 'General Purpose', include values for Heat of Respiration.
